-### I want to use Polaris v13.0.0 or higher
-
-Currently, this template is set up to work on node v18.20 or higher. However, `@shopify/polaris` is limited to v12 because v13 can only run on node v20+.
-
-You don't have to make any changes to the code in order to be able to upgrade Polaris to v13, but you'll need to do the following:
-
-- Upgrade your node version to v20.10 or higher.
-- Update your `Dockerfile` to pull `FROM node:20-alpine` instead of `node:18-alpine`
